There appears to be a memory leak that was introduced in 4.0.3512.2008. After upgrading from 4.0.3509.2008, I noticed my application running out of memory. Using the .NET Memory Profiler application, I noticed lots of SpreadView objects still in memory. Rolling back to 4.0.3509.2008 fixed the problem.
After some investigation, it appears there is an event handler related to the skins that is not getting properly unsubscribed.
Please address ASAP. In the meantime, I will be rolling back to the previous version.
